Remote exploitation of an integer overflow vulnerability
in the smbd daemon included in Samba 2.0.x, Samba 2.2.x,
and Samba 3.0.x prior to and including 3.0.9 could
allow an attacker to cause controllable heap corruption,
leading to execution of arbitrary commands with root
privileges.

In order to exploit this vulnerability an attacker must possess
credentials that allow access to a share on the Samba server.
Unsuccessful exploitation attempts will cause the process
serving the request to crash with signal 11, and may leave
evidence of an attack in logs.

The updated packages have been patched to correct this issue.
